ISO 45001 — The Fundamentals
ISO 45001:2018 is the replacement to OHSAS 18001 and is the international ISO standard for Occupational Health and Safety Management Systems (OHSMS).
Not only has the standard superseded OHSAS 18001, it makes integration with other management systems simpler than ever before; because it shares the common structure defined by Annex SL, it is directly aligned with the 2015 versions of ISO 9001 and ISO 14001.
You can find more information about this standard and the differences to OHSAS 18001 in the NQA ISO 45001 Gap Guide below. Please note: Existing NQA OHSAS 18001 clients can get migration support and can download the gap analysis document that must be completed prior to a migration audit.

Steps to Certification
Complete a Quote Request Form so that we can understand your company and requirements. You can do this by completing either the online quick quote or the online formal quote request form. We will use this information to accurately define your scope of assessment and provide you with a proposal for certification.
Once you’ve agreed your proposal, we will contact you to book your assessment with an NQA Assessor. This assessment consists of two mandatory visits that form the Initial Certification Audit. Please note that you must be able to demonstrate that your management system has been fully operational for a minimum of three months and has been subject to a management review and full cycle of internal audits.
Following a successful two stage audit, a certification decision is made and if positive, then certification to the required standard is issued by NQA. You will receive both a hard and soft copy of the certificate. Certification is valid for three years and is maintained through a programme of annual surveillance audits and a three yearly recertification audit.
